Diagnosis (simple): Apostolepis albicollaris Lema, 2002 is easily diagnosable from all its congeners by the following combination of characters: a distinctive white nuchal collar (bordered by a narrow black collar), a very broad black lateral streak (from ventral border to 5th dorsal row), an almost entirely black ventral surface or black with lateral blotches, and 5th + 6th supralabials in contact with the parietal (temporals 0 + 0).
